Barriers to obesity communication - Power, habitus and hidden assumptions

Communication on health issues often founders on the avoidance or denial of key messages by intended recipients. This paper explores the development and application of a research methodology combining elements of Pierre Bourdieu’s work on the unconscious nature of practice with Gerhard Maletzke’s psychological model of communication. This combination was designed to elicit deeper responses than those often found in health communication research. This alternative methodological approach was used to evaluate a year-long, city-wide anti-obesity campaign in Sheffield, UK, which targeted key gatekeepers in the message chain; their responses generate useful insights into resistance to uncomfortable communication. The paper concludes with suggestions for addressing communication about obesity and potentially other uncomfortable health and social topics

Artificial intelligence in communication management : a cross-national study on adoption and knowledge, impact, challenges and risks

Purpose Artificial intelligence (AI) might change the communication profession immensely, but the academic discourse is lacking an investigation of the perspective of practitioners on this. This article addresses this research gap. It offers a literature overview and reports about an empirical study on AI in communications, presenting first insights on how professionals in the field assess the technology. Design/methodology/approach A quantitative cross-national study among 2,689 European communication practitioners investigated four research questions: RQ1 – How much do professionals know about AI and to what extent are they already using AI technologies in their everyday lives? RQ2 – How do professionals rate the impact of AI on communication management? RQ3 – Which challenges do professionals identify for implementing AI in communication management? RQ4 – Which risks do they perceive? Findings Communication professionals revealed a limited understanding of AI and expected the technology to impact the profession as a whole more than the way their organisations or themselves work. Lack of individual competencies and organisations struggling with different levels of competency and unclear responsibilities were identified as key challenges and risks. Research limitations/implications The results highlight the need for communication managers to educate themselves and their teams about the technology and to identify the implementation of AI as a leadership issue. Originality/value The article offers the first cross-national quantitative study on AI in communication management. It presents valuable empirical insights on a trending topic in the discipline, highly relevant for both academics and practitioners

Turn Around When Possible: Mapping European Communication Competences

Purpose: This synopsis of the European Communication Professional Skills and Innovation (ECOPSI) benchmarking Interim Report explains the complex landscape of competencies required by European communication practitioners and explores the underlying constructs that contribute to competence namely skills, knowledge and personal attributes. Design/methodology/approach: Through a partnership, the methodology draws on the expertise of six leading European universities in communication research around a common goal of mutual interest. The research approach draws on a systematic literature review along with an extensive desk research benchmarking technique conducted by each of the partners. The study builds on prior research on skills and knowledge of communication practitioners. Findings: The findings highlight gaps in knowledge about the specific competencies required by European communication practitioners and will underline the current contemporary issues faced by the profession. This information served as the framework for the ECOPSI program (an EU funded research project). Practical implications: The synopsis increases awareness of the competence and capability factors of communication professionals in Europe to key stakeholders. It aims to increase understanding of the training and development needs of communication practitioners across Europe. Social implications: The synopsis highlights what practitioners consider to be important skills, knowledge and personal attributes across different countries which is essential in today’s globalized industry. This contributes to EU mobility targets and expectations for European workers. Originality/value: This study benchmarks the educational and practice landscape in six key regions of Europe to demonstrate that the elements focusing on skills, knowledge and personal attributes of European communication professionals can be synthesized using competencies as the foundational element

Scanning Tunneling Microscope Images of Adenine and Thymine at Atomic Resolution

The scanning tunneling microscope has been used to obtain images of DNA that reveal its major and minor grooves and the direction of helical coiling, but sufficient resolution has not yet been achieved to identify its bases. To determine if this technology is capable of identifying individual DNA bases, we have examined the molecular arrangements of adenine and thymine attached to the basal plane of highly oriented pyrolytic graphite. Both molecules form highly organized lattices following deposition on heated graphite. Lattice dimensions, structural periodicities, and the epitaxy of adenine and thymine molecules with respect to the basal plane of graphite have been determined. Images of these molecules at atomic resolution reveal that the aromatic regions are strongly detected in both molecules while the various side-groups are not well-resolved. These studies provide the first evidence that tunneling microscopy can be used to discriminate between purines and pyrimidines

Between a rock and a hard place: publishing issues in public relations and communication management

Purpose The purpose of this paper is to explore the pressures to publish facing European public relations (PR) and communication management scholars across career stages. Design/methodology/approach The Delphi method was used with PR and communication management scholars at associate professor level or higher across Europe. An online survey was then shared with the wider academic community to gather insights from scholars at different career stages. Findings The suitability and status of the journal and the language of the outputs are considered. Academics are caught between the rock of publishing inside the field to support its development and the hard place of being required to publish in high-ranking journals for funding and promotion. Scholars are evaluated regularly, with journal articles being the main unit of assessment. Academics, regardless of career stage, feel under pressure to publish. Research limitations/implications The wider survey enabled publishing insights to be gathered from academics across the career spectrum, but it was completed by a small sample. Nevertheless, similar concerns emerged from both methods of data gathering, suggesting a clear agenda for discussion and further research. Practical implications PR and communications management is an academic discipline without an accepted list of high-impact journals. This study provides an annotated journal list to aid institutional evaluations, aid scholarly journal publishing decisions and support early career researchers navigating the publishing process. Originality/value This adds to the somewhat limited discussion regarding how academics in PR and communication management decide where to publish and provides a resource that can be used by scholars, institutions and funders

Coordinate based random effect size meta-analysis of neuroimaging studies

Low power in neuroimaging studies can make them difficult to interpret, and Coordinate based meta-analysis (CBMA) may go some way to mitigating this issue. CBMA has been used in many analyses to detect where published functional MRI or voxel-based morphometry studies testing similar hypotheses report significant summary results (coordinates) consistently. Only the reported coordinates and possibly t statistics are analysed, and statistical significance of clusters is determined by coordinate density. Here a method of performing coordinate based random effect size meta-analysis and meta-regression is introduced. The algorithm (ClusterZ) analyses both coordinates and reported t statistic or Z score, standardised by the number of subjects. Statistical significance is determined not by coordinate density, but by a random effects meta-analyses of reported effects performed cluster-wise using standard statistical methods and taking account of censoring inherent in the published summary results. Type 1 error control is achieved using the false cluster discovery rate (FCDR), which is based on the false discovery rate. This controls both the family wise error rate under the null hypothesis that coordinates are randomly drawn from a standard stereotaxic space, and the proportion of significant clusters that are expected under the null. Such control is necessary to avoid propagating and even amplifying the very issues motivating the meta-analysis in the first place. ClusterZ is demonstrated on both numerically simulated data and on real data from reports of grey matter loss in multiple sclerosis (MS) and syndromes suggestive of MS, and of painful stimulus in healthy controls. The software implementation is available to download and use freely

Sceptical Employees as CSR Ambassadors in Times of Financial Uncertainty

This chapter offers new insights into the understanding of internal (employee) perceptions of organizational corporate social responsibility (CSR) policies and strategies. This study explores the significance of employees’ involvement and scepticism upon CSR initiatives and focuses on the effects it may have upon word of mouth (WOM) and the development of employee–organisation relationships. Desk research introduces the research questions. Data for the research questions were gathered through a self-completion questionnaire distributed in a hardcopy form to the sample. An individual’s level of scepticism and involvement appears to affect the development of a positive effect on employees’ WOM. Involvement with the domain of the investment may be a central factor affecting relationship building within the organization, and upon generation of positive WOM. The chapter offers a conceptual framework to public relations (PR) and corporate communications practitioners, which may enrich their views and understanding of the use and value of CSR for communication strategies and practices. For-profit organisations are major institutions in today’s society. CSR is proffered as presenting advantages for (at macro level) society and (micro level) the organization and its employees. Concepts, such as involvement and scepticism, which have not been rigorously examined in PR and corporate communication literature, are addressed. By examining employee perceptions, managers and academic researchers gain insights into the acceptance, appreciation and effectiveness of CSR policies and activities upon the employee stakeholder group. This will affect current and future CSR communication strategies. The knowledge acquired from this chapter may be transferable outside the for-profit sector

Experimental constraints on a dark matter origin for the DAMA annual modulation effect

A claim for evidence of dark matter interactions in the DAMA experiment has been recently reinforced. We employ a new type of germanium detector to conclusively rule out a standard isothermal galactic halo of Weakly Interacting Massive Particles (WIMPs) as the explanation for the annual modulation effect leading to the claim. Bounds are similarly imposed on a suggestion that dark pseudoscalars mightlead to the effect. We describe the sensitivity to light dark matter particles achievable with our device, in particular to Next-to-Minimal Supersymmetric Model candidates.Comment: v4: introduces recent results from arXiv:0807.3279 and arXiv:0807.2926. Sensitivity to pseudoscalars is revised in light of the first. Discussion on the subject adde

Large-Mass Ultra-Low Noise Germanium Detectors: Performance and Applications in Neutrino and Astroparticle Physics

A new type of radiation detector, a p-type modified electrode germanium diode, is presented. The prototype displays, for the first time, a combination of features (mass, energy threshold and background expectation) required for a measurement of coherent neutrino-nucleus scattering in a nuclear reactor experiment. The device hybridizes the mass and energy resolution of a conventional HPGe coaxial gamma spectrometer with the low electronic noise and threshold of a small x-ray semiconductor detector, also displaying an intrinsic ability to distinguish multiple from single-site particle interactions. The present performance of the prototype and possible further improvements are discussed, as well as other applications for this new type of device in neutrino and astroparticle physics (double-beta decay, neutrino magnetic moment and WIMP searches).Comment: submitted to Phys. Rev.

Lesion topography and microscopic white matter tract damage contribute to cognitive impairment in symptomatic carotid artery disease

Purpose: To investigate associations between neuroimaging markers of cerebrovascular disease, including lesion topography and extent and severity of strategic and global cerebral tissue injury, and cognition in carotid artery disease (CAD). Materials and Methods: All participants gave written informed consent to undergo brain magnetic resonance imaging and the Addenbrooke’s Cognitive Examination–Revised. One hundred eight patients with symptomatic CAD but no dementia were included, and a score less than 82 represented cognitive impairment. Group comparison and interrelations between global cognitive and fluency performance, lesion topography, and ultrastructural damage were assessed with voxel-based statistics. Associations between cognition, medial temporal lobe atrophy (MTA), lesion volumes, and global white matter ultrastructural damage indexed as increased mean diffusivity were tested with regression analysis by controlling for age. Diagnostic accuracy of imaging markers selected from a multivariate prediction model was tested with receiver operating characteristic analysis. Results: Cognitively impaired patients (n = 53 [49.1%], classified as having probable vascular cognitive disorder) were older than nonimpaired patients (P = .027) and had more frequent MTA (P<.001), more cortical infarctions (P = .016), and larger volumes of acute (P = .028) and chronic (P = .009) subcortical ischemic lesions. Lesion volumes did not correlate with global cognitive performance (lacunar infarctions, P = .060; acute lesions, P = .088; chronic subcortical ischemic lesions, P = .085). In contrast, cognitive performance correlated with presence of chronic ischemic lesions within the interhemispheric tracts and thalamic radiation (P< .05, false discovery rate corrected). Skeleton mean diffusivity showed the closest correlation with cognition (R2 = 0.311, P< .001) and promising diagnostic accuracy for vascular cognitive disorder (area under the curve, 0.82 [95% confidence interval: 0.75, 0.90]). Findings were confirmed in subjects with a low risk of preclinical Alzheimer disease indexed by the absence of MTA (n = 85). Conclusion: Subcortical white matter ischemic lesion locations and severity of ultrastructural tract damage contribute to cognitive impairment in symptomatic CAD, which suggests that subcortical disconnection within large-scale cognitive neural networks is a key mechanism of vascular cognitive disorder
